The region is mainly underlain by the Paleozoic to Tertiary Coast Plutonic Complex consisting predominantly of crystalline rocks which exhibit a variety of fabrics ranging from pre-to post- kinematic. Paragneisses of (?)Paleozoic age, younger deformed metasediments and volcanics related to the Stikinia Terrane are interspersed within the plutonic complex. The northeastern part of the Bella Coola map area is underlain primarily by mafic volcanic and sedimentary rocks of the Jurassic Hazelton Group. These rocks are variably deformed containing both northeast and northwest trending structures.

The Russ showing occurs in an area underlain by foliated quartz diorite, diorite and granodiorite related to a batholith of possibly Triassic age. Mineralization consists of molybdenite, chalcopyrite, pyrite and magnetite in quartz veins. No other geological informa- tion is available.
